Desenvolvimento de uma técnica ótica para digitalização do solo após o contato rodado-solo

Abstract

Soil is a natural body composed by parcels in solid, liquid and gaseous that contains living matter and occupy the greater portion of the earth surface. They soil allows the agriculture development, essential and irreplaceable for human life, and the adoption of the mechanization has been important to get higher productivities, therefore supplementing the demand of the global population which increases each day. However, the intense use of machinery and implements in agriculture requires knowledge of their interaction with the soil, in order to avoid the damages possible damage its structure, which brings problems to the-development of the cultures and brings ambient impacts. In this context, it is necessary to understand the effects of the that tires from the tractors can cause during the transit on agricultural areas, where the non-invasive techniques which can also be of-simple and fast implementations are potential tools to analyze those impacts. This study evaluated the Moiré technique as a potential alternative to the traditional manual processes presenting a protocol of digitalization of the soil in field, and presenting the viability of a construction of a laser scanner. The results showed the feasibility of the moiré technique digitizing the soil in the laboratory and in the field, in addition the work validated the use of a proposed laser scanner.
